... Arid zone landscapes are characterised by a high spatial and temporal variability, particularly seasonal variability, observable on a range of scales. This variability is an important factor influencing the distribution and dynamics of wildlife populations in the arid zone. However, progress...

... of the total data. Wetlands that were surveyed more than once over the course of a year, and at which Southern Bell Frogs were recorded at least once were analysed for seasonal variability in detection rate. This revealed that 92% of surveys conducted in November (n = 26) detected calling frogs compared to 50...

The variability in results highlights the complexity of patterns in dingo scavenging and, more broadly, of vertebrate...
